In Canada December 30, 1944 8 Claims. v '(Cl. 242 -68) In the art ofpaper making, winding reels are employed for the purpose of winding thepaper web thereon as it comes from the calender rolls of the papermaking machine without interfering with the continuous run of paper fromthe machine. It is common practice therefore in winding operations todispose a winding reel on each side of the winding drum and when a givenquantity of paper is wound upon one reel the opposite reel is started,brought up to winding speed and the paper web or sheet then switchedfrom the full to the empty reel without interfering with the continuouspaper run.

The starting or rotating operation of the empty reel on the machineside, commonly referred to as angle that only one side or end thereofcontacts the winding drum and such contact is outside the travel limitsof the moving paper web. From this position the reel is lowered withsuflicient contact or drag on the drum to induce it to first rotate andthen attain a rotative speed corresponding to-that at which the drum isrotating. The full length of the reel is then lowered into as nearly aparallel position with the drum as possible and into contact with thepaper web passing over the drum.

The operation of contacting one end of the winding reel with one end ofthe rotating drum for reel starting purposes and then endeavouring tolower the full length of the reel into even contact with the movingpaper web frequently cracks or breaks the edge of the web or sheet andin the event these cracks or breaks are of a- 7 web-straddling meanswhich may be started and brought up to rotation at the required windingj speed before being fully brought into engagement with the web thusavoiding cracking ,or

2 r, breaking the paper web and the resulting substantial loss of paper,and waste of time and further eliminates the danger of workmens clothingbeing entangled therewith. v

Yet a further object of the present invention is to provide a device ofthis character which is simple and ruggedinform and one that will themore satisfactorily perform the functions required of it.

Having regard to the foregoing and other ob-- jects and advantages whichwillbecome apparent as the description proceeds, the invention consistsessentially in the novel combination and arrangement of partshereinafter described in detail and illustrated in the accompanyingdrawings in which:

Figure 1 shows anend view of anembodiment of the present invention whichfor purposes of illustration is shown in operative position on thedry-end of a paper machine.

Figure 2 is a plan view of the present invention' shown in detachedform.

Figure 3 is an enlarged sectional view taken on the line 3-3 of Figure2, and

Figure 4 is a section taken on the line 4-4 of Figure 3,

Referring now to the accompanying drawings disclosing an embodiment ofthe present invention and wherein like letters and numerals of referencedesignate corresponding parts in the different illustrations, the letterA indicates the present invention as a whole while the letter Bindicates a fragmentary portion of the dry-end" of a'paper makingmachine.

For operative purposes the winding reels A are removably supported inany suitable type of end bearings l5 by arm means IS, the arms l6 beingswingably connected to the frame of the paper making machine B as at IT.Suitable and well known mechanism is provided for swinging arms IS withreels A thereon toward winding drum l8 for purposes of starting and thenbringing the reel up to proper rotative speed as will be laterexplained.

The winding reel herein disclosed includes a casing or shell IQ ofappropriate length and suitable material having end supporting shafts 20all of which is known in the art.

In accordance with the present invention, each end of the winding reel Ais provided with yieldably mounted contact collars or discs 2! whichbody of reel l9 so that when the reel A is lowered into contact with thewinding drum I8 for purposes of starting the rotative movement of thereel, the collar members straddle the paper web and contact the drumoutside the limits of such paper web. Here it is considered proper tomention that by reason of the annular structure of the disc members,their rounded edges and the fact that they protrude a limited extentbeyond the surface of the reel body, eliminates the danger of workmenbecoming entangled therewith.

Each of the collar members or discs 2| is constructed with a centralbore or openin 22 the diameter of which is greater than the outsidediameter of the shafts 20 while a series of concentrically arrangedbores or openings '23 are formed between the inner and outer peripheriesof the collar members. Within the openings 23 of the collars I mountannular sleeves 24 composed of rubber or like yieldable material whilewithin the core of the members 24 I mount metallic spacer rings orsleeves 25 that, are just a little longer than the thickness of thediscs 25 and yieldable sleeves 24.

The means for mounting the collar members 2| on the ends of the reel Ato efiect a floating mounting comprise end plates 26 which are fittedover the shafts 20 at the outside of collars 2i and are connected to thereel A as by countersunk bolts. or the like 21. These bolts it isobserved extend through the metallic spacer rings,- with their necessarymargin of length over the thickness of the collars 2 I, and into theends of the reel head, thereby maintaining the collars in floatingrelationship to reel A.

With the resilient members 24 disposed between the collar or discmembers 2| and bolts 27, the mountings will yield when a pressure isimposed on the outer periphery of the discs or collars however in theabsence of a peripheral pressure the discs are maintained in a normalposition such as seen in Figures 2 and 3, so that they en- ,gage theends of the rotating drum for reel rotating purposes without contactingthe paper web.

From the foregoing it will be observed that the full length of the reelis lowered parallel with the drum 18 until the disc members contact thedrum outside the limits of the moving paper wab and the reel is quicklybrought up to rotative winding speed. With this accomplished the reel islowered into tight parallel contact with the moving paper web, theyieldable mountings enabling the disc members to ride the drum in thesame plane as the reel body. This precise and accurate lowerin of thereel enables it to move into tight, even contact with the moving paperweb at a corresponding speed and without crack ing or breaking the papersheet. Simultaneous with the lowering of the full weight of the reel,air jets are operated to break the paper web and, turn it on the emptyrotating winding reel, without interfering with the continuous run ofpaper from the paper making machine.

Many changes may be made in the above and many apparently widelydifferent embodiments constructed without departing from the spirit oressential characteristics of the invention. It is intended thereforethat the present disclosure be interpreted as illustrative rather thanrestrictive and that all changes coming within the meaning and range ofequivalency of the claims are intended to be embraced therein.
